- Cambodia, Laos, Myanmar and Vietnam eliminated some 90% of their tariff lines in 2015, and 97% in 2018.

Vietnam already cut nearly 6,900 tariff lines, or 72% of all tariff lines, to zero% in 2014. It slashed more than 1,700 other lines to zero% in 2015, the finance ministry said late last year.

Further, it said the country would cut nearly 700 remaining tariff lines, mainly "sensitive commodities", to zero% by 2018. Among these are automobiles and spare parts, vegetable oil, refrigerators, air-conditioners and dairy products.

Vietnam and China held the ninth round of negotiations of a working group on the sea area beyond the mouth of the Gulf of Tonkin and the sixth round of negotiations of a working group on cooperation in sea development in the central city Da Nang, on March 15-16.
